Abstract (en)

[origin: EP0971428A2] A fuel cell (1) has a plurality of passages for conveying a fluid in a stack (12) formed of a plurality of unit cells (10). The connection of the passages is changed in accordance with the operating condition of the fuel cell (1). If the passage connection is thus changed, the passage resistance in the stack changes, so that an optimal performance of the fuel cell (1) can be achieved in accordance with the operating condition thereof. <IMAGE>
